WALL FORM.

Application filed December 9, 1922.

Be it, known that l, Linnrr lil. MCCAL- 1.1m, a citizen ol' the United States, residing` al Ypsilanti, in the count.;l of 'ashtenaw and l'tate oiA Michigan. have invented new and useful Improvements in Wall Forms. ol' which the following is a specilit-ation.

This` invent ion relates to a i'iorin Vfor huildin;V concreto walls. ceilings and floors, the `general object. of the invention hein;r to so l'orni the parts that they can be easily and quickly put in place to Form either single or donhlc walls, the parts being entire-l5T formed of metal and connected together hy bolts so that they can he used over and over again.

Another object ol' 'the invention is to provide concrete spacers lor the walls o'lE the forni through which the tie holte pass. said spacers having recesses therein l'or rereivinpr the heads olt the permanent tie bolts and tie plates, said recesses lacing?r adapted to he filled with cement so as to cover np the plates and bolts and thus leave no metal part upon the surface of the wall.

This invention also consists in rertain other features ot construction and in the combination and arrangement ol the several parts. to be hereinafter fully described, illustrated in the accompanying drawings and speeiiccall)T pointed ont in the appended claims.

ln describing my invention in detail. reference will he had to the accompanying drawings wherein like characters denote like or correspondin: parts throughout the several views. and in which Figure l is a side elevation of a portion of the invention.

Figure 2 is a view of one of the sections of the form.

Figure 3 is a top plan view of a form for a douhle wall. v

Fig-ure l is an end view of Figure 3.

Figures 5 and G are views of a corner portion of the form.

Figures 7, 9 and 9 are views ot the cement wall with the t'orrn removed.

is shown in these views the lorm consists oi a nlunher ol' sections each section consistingr o'f a numher of sheet metal plates l which are secured to thel vert-ical channel inemhers 2 and the horizontal channel inemhers i Xt one end ol'v cach Section the sheet l overlaps the end channel inemher 2. as shown at 4, while at the opposite end the Serial No. 605,863.

rhannel member overlaps the sheet, as shown at i. nhns the. end channel members` ol two abuttingI sefitions` will engage cach other with the owriapping part l oi' one section engaging the space formed by the overlapping part nl the other section so that a tight connection is formed between the sertions. 'lf'he top and bottom parts ol each section are also l'orincd with these overlappiner portions. as shown7 so that one section can he placed upon the top of another. Angle-shaped liners 6 arc placed at the hottonn` and centers of the sections and channelshaped lines 7 at the top of the upper tier of sections. 'l'he tie bolts 8 pass through the` liners. l also provide spreaders 9 which taper from the center towards each end and which I.1re provided with the recesses lll in their outer ends. rthese spreaders are prelerahl)` Yi'ornied ot' cement and are hored or cored to receive the tie bolts. These spreaders are, placed between the sections of each wall and v; hen the wall is to he of double construction with a space between the two walls l provide small spreaders 11 which are placed hetween the inner sections of the two forms and which are bored or cored to receive the tie bolts. When the forms are to he removed the sections 11 are broken to permit the inner sections to he removed after the tie. holts are withdrawn. A cap 12 is provided lorcovering the space between the two inner sertionsotthe forms. said rap heinp'l formed ot' a piate i3 secured to a channel iron '14. This rap also acts as a spacer for the two inner members as well as to prevent material irom dromjing into the space between the two members. liner clamp 15 formed ol' channel iron is also provided for clainpinpY the tops ot the iorlns together. The depending ends oi this clamp engage the liners 7. Home olE the sections are formed of angle shape. as shown at 1G. to form the corners ol the walls and I also provide short sections 17 which are used for inserts when necessary. The sections are provided with holes 18 for receiving the tie holts S.

From the foregoing it will he seen that the forms can be easil;Y and quicklyv sel` up and the walls thereofY are held in spaced relation h v the spreaders and liners. the spreaders 9 and 11 acting to receive the tie bolts, t'ter the walls are formed the spreaders 11 are hrolren and then the tio holes withdrawn and the sections of the forms removed. Tie plates are then pl ared in the recesses l() and permanent tie holle passed through the hores oi' the splendere` and liolted in place. The recesses l() :ire then filled with Cement so that the tie holts :1nd plates :1re embedded in the walls :and :ire hidden from vien' :ind cannot mar the snri'ure oi' the walls through rust und the like.

In the double well eonstriirlion the :iir spare is continuons sind this sinn-e :if-ts lo multe the lmildinfj eooler in slimmer sind' warmer in winter and i also mnlzes the walls lmnp prooi. All !he WalleA me poured :1t the sume time. marking a solid monolilhi.` ionstrnrtion. `is the forms :ire easily :1nd imielrlj: assembled and dissembled the c011- strlietion cost is low :ind :is the i'orms :lire oi' steel they muy he need over und over signin. They :ire also nszihle ior :ilnioFt :my type of huil-ding. llnslrillefl lzehor een he used und the r'ost oi' lmndlingI the miiierinl is reduced.

lt is thought from the 'foregoing flesi'rin tion that the advantage@ and novel tentures: of my invention will he rendiljv apparent.

l desire it to he nndensftnod that lY muy mnle Changes in the eonetrnetion and in the Combination and arrangement oi the several parte. provided that sneh vhnnges fall Within the seope of the appended claims,

lVhat I claim is l. A iorm of the Class desr'rilwd rompi-isingr :i plurality of sertions` enf-h formed oic sheet metal plates and elimine-l memhers to Whirh the plates are eonnerted.` liners tor the seetions. rement snrenders for the Walle of the form through Which the trie bolts pass, said spreaders having recesses therein Yl'or receiving the ends of the, permanent tie bolts and their tie planes and a filling of vement so thin the tie holts will he embedded in the. finished wall.

A form of the Class described vomprising two pairs oit wells` spreaders i'or spur innr the inner walls apart. spreziders for spacing the outer Wells from the inner walls, said spronders heiligr bored or eored to receive the tie bolts and the outer spreaders haring recesses in their outer ends for receiving the ends of the permanent tie. bolts :ind their tie plates and n filling ot vement. il. form ol' the (dass deserihed comprisin#r two sots of walls. spreuders for epe" ingr the. inner Walls apart, snreaders for spacing? the exterior walls from the inner Wells, said splendere hein@ lmred or cored to receive the tie bolts, a eap-spueer for engaging the upper edges of the interior wells ior covering the space between the `two Walls und clamps for holding* the Walls togethelx 4. A form of the Class described comprising wells formed of a, plurnlitir of metal elections` liners associated with the. sections of the outer walls, tie holte for connecting the Walls together, said bolts engaging some of the liners. spreaders for the walls through which the bolts pass, clamps at, the. upper edges of the walls and having de pending ende engagingthe top liners.
